Wendan decoction for dyslipidemia: Protocol for a systematic review and meta-analysis.

BACKGROUND

Dyslipidemia is one of the most popular metabolic diseases and an important risk factor for arteriosclerotic cardiovascular diseases. In China, Wendan decoction (WDD) has been widely used to treat hyperlipidemia. However, no systematic review has been found. In order to evaluate the efficacy and safety of WDD in the treatment of dyslipidemia, a meta-analysis and systematic evaluation are conducted.

METHODS

The randomized controlled trials (RCTs) evaluating the effectiveness and safety of WDD in the treatment of dyslipidemia will be enrolled. Data are mainly from 4 English databases (Pubmed, Embase, Cochrane Library, and Web of science) and 4 Chinese databases (Wanfang, CBM, CNKI, and VIP Database). The enrollment of RCTs is from the starting date of database establishment till December 15, 2018. Low density lipoprotein cholesterol is considered as the main outcome, while the serum concentrations of total cholesterol, triglyceride, high density lipoprotein cholesterol, apolipoprotein A, and apolipoprotein B are regarded as the secondary outcome. Safety indicators include liver enzyme, fasting blood glucose, and kidney function. The work such as selection of literature, data collection, quality evaluation of included literature, and assessment of publication bias will be conducted by 2 independent researchers. Meta-analysis will be performed by RevMan 5.0 software.

RESULTS

This study will provide high-quality evidence for the treatment of dyslipidemia with WDD in terms of effectiveness and safety.

CONCLUSION

The results of the study will help us determine whether WDD can effectively treat hyperlipidemia.
